ELECTRICALLY PROPELLED DISPLAY DEVICE WITH SIMULATED HOVERING AND/OR FLYING PATTERNS
The present invention is referred to an electrically propelled display device with simulated hovering and/or flying patterns, comprising a driving unit; said driving unit includes a base, a central hollow body and a rotatable head. A power source is connected to the driving unit, a flexible support is attached to the rotatable head of the driving unit and a display pattern is attached to the flexible support. Said driving unit includes in the central hollow body an oscillator electronic circuit and an electric motor. Said oscillator electronic circuit is connected to the power source and to the electric motor which includes a driving motor shaft attached to the rotatable head. This device simulates the movement of some flying objects and aliforms, such as birds, bats, butterflies, dragonflies, fairies, or the like. The oscillator circuit sends pulses at a certain frequency to the motor, generating an intermittent, rotational movement. This movement is transferred to the wire, which, then accentuates and transmits this movement to the object. The ultimate effect is the combination of a rotational movement, and a movement that simulates the flapping of wings of some flying animals and fairies, or the movement of other aquatic or terrestrial animals. The speed and intensity of rotation and flapping change with the frequency and pulse width of the wave that the oscillator sends. The device may be used in decorative, educational, promotional, and entertainment applications. It may be used both, indoors and outdoors.
This Continuation-in-Part application claims the benefit of co-pending U.S. Non-Provisional Patent Application Ser. No. 12/336,153, filed on Dec. 16, 2008, which is incorporated herein in its entirety.
BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates generally to display devices capable of creating the effect of a flying or hovering object, such as a bird, a butterfly, a bat, etc. More particularly, the present invention is referred to a display device propelled by an electric motor which in turn drives an elongated flexible support to which the flying or hovering object is mounted. Even more particularly, the present invention is referred to an electrically propelled display device with simulated hovering patterns.
2. Description of the Prior Art
Flying toys have been proposed in the past using different features and forms. Just as an example, flying dolls, helicopters, flying saucers and aircrafts are some of multiple examples known in the prior art. Also some of these examples allow the toy to hover in air through the use of helium-filled devices, chopper-like blades propelled by an electric motor or even water. But this hovering effect cannot be maintained for a long time, and it is just an effect that lasts few minutes.
U.S. Pat. No. 3,477,157 issued on Nov. 19, 1969 to E. G. Paquette entitled “Advertising Display” shows a device simulating a firefly mounted on a flexible support which in turn is anchored in an angularly oriented flippable holding member. The member is attached to a rotatable shaft having a loose connection and imparts a jerking motion on the member. However, the angular movement in this device is an irregular movement caused by the loose connections and the type of flippable holding member to which a steel spring is attached.
U.S. Pat. No. 4,180,932 issued on Jan. 1, 1980 to Millard entitled “Animated Plant Display” discloses an animated plant display defined by a housing which contains a rotating platform mounted on a shaft which is driven by a motor which can be operated by a battery. Flowers plants and bells are mounted on the platform and display with the form of a butterfly is mounted through a slot in a collar of the housing surrounding the platform. Said wire is supporting the butterfly and creates a vibration effect by a cog wheel mounted on the shaft which causes cogs to press against the wire supporting the butterfly. Another cog wheel mounted on the shaft causes a hammer mounted within the housing to gently hit a bell depending from a support within the housing, causing gentle bell like sounds while the butterfly moves around undulating as the platform rotates. This invention does not generate a rotational wire movement to direct the butterfly in an angular path, but rather the butterfly movement is constrained to a straight line.
U.S. Pat. No. 4,901,458 issued on Feb. 20, 1990 to Belokin et al. describes an advertising display including a simulated winged butterfly, bee or the like, and which is rotatable driven by a battery operated electromotor to simulate the flight of a butterfly and draw the customer's attention to the merchandise displayed therewith. The rotatable display includes a thin piano wire on which the butterfly is mounted at the upper end of the wire, the lower end of the wire being secured to a rotatable driven member in such a manner as to preclude breakage due to the repeated flexing. An upper end portion of the wire is bent so that the butterfly trails in the direction of rotation of the driven member and produces a particularly lifelike, articulated and swinging movement of the butterfly.
U.S. Pat. No. 4,949,486 issued on Aug. 21, 1990 to Belokin et al. illustrates a display unit for point of sale advertising comprising a stationary object, such as a real or simulated flowering plant, mounted on a support, such as a flowerpot, and a flying object, such as a simulated butterfly, operated by driving apparatus so as to move in a randomly undulating and randomly reversible orbit around the plant, as would a real butterfly. The driving apparatus comprises an electric motor having a motor housing stationary mounted on the flowerpot, a stator including a stationary field coil electrically energizable by alternating current mounted in the motor housing, and a rotor in the form of a bipolar permanent magnet rotatable mounted on an upright magnetizable metal shaft on the motor housing. The effect created with this invention is to cause the simulated butterfly to flutter about the flowering plant as would a real butterfly. However, a predetermined mechanical load imposed on the permanent magnet rotor effected by random striking of the simulated butterfly against the plant, or by random horizontal and vertical excursions of the simulated butterfly in its orbital path, or by random “hand-up” of the permanent magnet rotor on its shaft, causes the rotor to periodically and frequently reverse its direction of rotation.
U.S. Pat. No. 5,146,702, issued on Sep. 15, 1992 to Belokin Jr. describes a display unit simulating a flying object and having an electric motor mounted on a support structure. A rotatable driven member is engaged on the shaft of the motor and has a wire with a flying object attached thereto. When the driven member is rotated, the wire is swung around, and the object assumes a flying fluttering motion due to the vibrations through the wire from the motor. The object is drivingly rotated in a swinging and erratic motion around the unit but at much slower rate of rotation than the motor shaft and member. In this invention, the motor is not driven by an electronic control.
U.S. Pat. No. 5,823,844, issued on Oct. 20, 1998 to Markowitz describes a vibrating toy including a housing, a battery mounted within the housing, a motor mounted within the housing activated by the battery, a shaft driven by the motor, a mechanism on the shaft for imparting an eccentric vibration from the housing, a play element outside of the housing, and a mechanism for connecting the play element to the housing and through which the play element can receive vibrations generated from the mechanism that imparts the eccentric vibration. A weighted element attached to the shaft imparts an eccentric vibration transferred to the housing which in turn through contact vibrates a wire serving as the mechanism that connects to the play element.
U.S. Patent Application No. 20080207084 A1 filed by Schnuckle on Aug. 28, 2008 describes an apparatus hovering winged objects. The apparatus includes an elongate support and a driver with an output shaft that supports a first end of the support. The driver imparts an oscillating displacement to the first end of the support. A body is mounted at a second end of the support and wings are attached to the support at an offset distance from the body. The body is positioned near the second end to swivel or pivot in response to vibration of the support. The driver vibrates the first end at a frequency that shapes the support as a wave, and the frequency is selected or tuned such that the wings are displaced more than the body such by imparting a harmonic frequency on the support.
SUMMARY OF THE INVENTIONThe general purpose of this present invention is to provide a very economical and easy to use product, that may be used in decorative, promotional, educational, and entertainment applications, and that succeeds in closely imitating the natural movement of aliforms, such as a butterfly, a dragonfly, a bird, a bat or a fairy. Just as an example, a butterfly pattern, with the aspect and movement of a real butterfly, may be very attractive for decorating a garden, the windows of a local shop, or simply a home.
This invention is directed to a display device which creates the effect of flying or hovering objects comprising in general an electric motor, a flexible wire connected to one end of the motor shaft, a light object at the other end of the wire, an electronic oscillator, and a power source.
Another aspect of the present invention provides a display device propelled by an electric motor using, as a power source, batteries, an AC/DC adapter, or alternating current from a regular power outlet.
Yet another aspect of the purposed invention comprises an electronic circuit known as an oscillator connected to the motor. This circuit is responsible for generating a squared wave with a graduated frequency and pulse width according to the speed and intensity of the flapping movement that is desired for the flying object. Each pulse activates the motor for a time that lasts as long as the pulse. A series of short, consecutive pulses causes a series of short activations of the motor. When the wave frequency is higher, the pulses have a shorter duration, and, thus, the duration of activations of the motor is shorter. Visually, an effect similar to a vibration is produced. The variation of the relationship between the motor activating and shutting off from the wave may produce various oscillation effects in the motor shaft, such as, alterations in the rotational speed, or changes in the intensity of the object's flapping movement.
Also another aspect of this invention comprises a display device which includes means for changing the intensity of the vibration of the pattern. The wire to which the pattern is mounted is connected to the motor shaft. By altering the angle between the motor and the wire changes are produced in the intensity of the vibration of the wire, and thus, the object's movement. The rotational and oscillatory movement of the motor shaft is transmitted accentuated by the flexible wire, which finally transmits it to the flying object.
Yet another aspect provides a display device which moves around the unit creating a very realistic flying or hovering movement, similar to that of a butterfly, bird or bat. The display pattern must be light, and may be made of a plastic laminate, fabric, paper, or other flexible material that is able to show the vibration that comes from the wire.
In summary the present invention is referred to an electrically propelled display device with simulated hovering patterns, comprising a driving unit; said driving unit includes a base, a central hollow body and a rotatable head; a power source is connected to the driving unit; a flexible support is attached to the rotatable head of the driving unit; a display pattern is attached to the flexible support; said driving unit includes, in the central hollow body, an oscillator electronic circuit and an electric motor; said oscillator electronic circuit is connected to the power source and to the electric motor; and said electric motor includes a driving motor shaft attached to the rotatable head.
These and other aspects, features, and advantages of the present invention will become more readily apparent from the attached drawings and the detailed description of the preferred embodiments, which follow.
The preferred embodiments of the invention will hereinafter be described in conjunction with the appended drawings provided to illustrate and not to limit the invention, where like designations denote like elements, and in which:
Shown throughout the Figures, the invention is directed to an electrically propelled display device 100 with simulated hovering patterns, comprising a driving unit 200. Said driving unit includes a base 230, a central hollow body and a rotatable head 250. A power source 300 is connected to the driving unit 200 and a flexible support 420 is attached to the rotatable head 250 of the driving unit 200 and to a display pattern 400 as well. Said driving unit 200 includes in the central hollow body an oscillator electronic circuit 260 and an electric motor 210. Said oscillator electronic circuit 260 is connected to the power source 300 through a cable 320 and to the electric motor 210, and said electric motor 210 includes a driving motor shaft 214 attached to the rotatable head 250.
The power source 300 is connected to the unit 200 by means of a cable 320 which carries the electrical current to an oscillator circuit 260. Due to the signal generated by the oscillator circuit 260, the motor shaft 214 rotates clockwise intermittently, as shown by arrow 212. When the oscillator circuit 260 generates a wave, a vibration is produced in the support 420, and due to its flexible nature, amplifies the vibration which is transmitted to the display pattern 400 located at the upper end 430 of the support 420.
Both, the vibration transmitted to the object 400 and the air that passes through it due to the rotation, cause the movement of the moving or flexible parts of the object 400, such as the wings 450, which may be made of plastic, metal, paper, fabric, or similar material.
A cylindrical fastening bar 220 is used to fix the device 100 to the ground 512 or other soft material. This bar 220 may be disconnected from the device 100 when the user wishes to place the unit 200 on a flat hard surface, such as on a table, supported on its base 230.
While the preferred embodiments of the invention have been described above, it will be recognized and understood that various modifications can be made in the invention and the appended claims are intended to cover all such modifications which may fall within the spirit and scope of the invention.
